Mac OS X Lion

I installed it, and I like it.

In general, I like to do a scorched Earth clean install to clean out cruft and avoid the traditional bugs that occur with an OS install done in place, but I decided to try the in place route.  After backing up with SuperDuper!, and burning a DVD of the Lion installation image (this will probably be handy some day), I installed Lion and it was ready in about a 1/2 hour.  No problems, although if you do Utilities -> System Information -> Software -> Applications, you can see PowerPC apps that won't work anymore (no Rosetta in Lion).  I didn't care about any of them anymore.  I also abandoned Quicken last year, so I didn't have that problem to deal with.

I suffered from mouse dyslexia for a day (because Lion reverses the convention for scroll direction to become more consistent with the touch devices), and then decided to get a Magic Trackpad, which gives me much more function than my Magic Mouse.  I am still don't know if the Natural Scrolling is really natural, but I will give it some more time.

I found a great article (more like a book) about Lion, both the exterior features as well as the internals, including commentary, written by John Siracusa at Ars Technica.  It was such a good source of info about security issues, Objective-C memory management strategies, recovery partitions, whole disk encryption, and other meaty issues that I splurged and got the eBook version from Amazon for $4.99.
